Elon Musk renews his battle with Delta after it snubbed Starlink for Jeff Bezos' Amazon Leo

Elon Musk argued that Delta would lose customers by not choosing Starlink.

Elon Musk has frequently criticized the decision and said Delta would lose customers.

"It will get much worse," Musk replied to an X post about passengers picking rivals with Starlink over Delta.

Elon Musk isn't over Delta Air Lines choosing a rival in-flight WiFi provider instead of Starlink.

After some X users posted about choosing to book with United Airlines over Delta due to its Starlink internet , Musk said on Wednesday, "I warned them.

It will get much worse." It comes after Musk said Delta would "lose customers" when the airline announced a deal with Amazon Leo in May.

Leo operates similarly to Starlink, using a constellation of satellites in low Earth orbit.

This means they provide stronger, faster connections because the satellites are closer to the planet and cover more areas than traditional in-flight WiFi providers.

When it comes to scale, Starlink is well ahead, with over 10,000 active satellites and deals with 43 airlines.

Amazon Leo has just under 400 satellites and aims to launch over 3,000.

It has only two announced airline customers so far — JetBlue and Delta.

Amazon plans to start the service with JetBlue next year and is scheduled to be available on Delta in 2028.

There's no evidence to suggest that customers eschewing Delta for other airlines with Starlink is widespread, though SpaceX President Gwynne Shotwell said during its recent earnings that one airline, which she didn't name, had reported some customers were choosing unnecessary layovers to ensure they were on a flight with Starlink .
